Adab (Arabic: أدب‎) in the context of behavior, refers to prescribed Islamic etiquette: "refinement, good manners, morals, decorum, decency, humaneness".[1] While interpretation of the scope and particulars of Adab may vary among different cultures, common among these interpretations is regard for personal standing through the observation of certain codes of behavior.[2] To exhibit Adab would be to show "proper discrimination of correct order, behavior, and taste."[2]

Islam has rules of etiquette and an ethical code involving every aspect of life. Muslims refer to Adab as good manners, courtesy, respect, and appropriateness, covering acts such as entering or exiting a washroom, posture when sitting, and cleansing oneself.

Customs and behaviour[edit]

Practitioners of Islam are generally taught to follow some specific customs in their daily lives. Most of these customs can be traced back to Abrahamic traditions in pre-Islamic Arabian society.[3] Due to Muhammad's sanction or tacit approval of such practices, these customs are considered to be Sunnah (practices of Muhammad as part of the religion) by the Ummah (Muslim nation). It includes customs like:

Saying "Bismillah" (in the name of God) before eating and drinking.[4]

Using the right hand for drinking and eating.[5]

Saying "As-Salaam Alaikum" (peace be upon you) when meeting someone and answering with "Wa 'alaikumus salam" (and peace be upon you).[6]

Saying "Alhamdulillah" (all gratitude is for only God) when sneezing and responding with "Yarhamukallah" (God have mercy on you).[7]

Saying the "Adhan" (prayer call) in the right ear of a newborn and the Iqama in its left.

In the sphere of hygiene, it includes:

Clipping the moustache

Removing armpit hair regardless of gender

Cutting nails

Circumcising the male offspring[8][9]
